Payments for Watershed Services: Pilot Projects for Watershed Protection

Forested watersheds of the southern United States provide numerous services to the region. At no cost, they purify water, control flooding and erosion, and provide places for people to relax and have fun. Yet despite their value, many watersheds are under threat from development and poor land management.

“Payments for Watershed Services” (PWS) programs are one strategy to keep watersheds healthy. Through a PWS program, landowners receive financial incentives to conserve, sustainably manage, and/or restore watersheds to yield the kinds of benefits described above.

Aqueduct News Roundup: The Importance of Water Data, and the Hidden Prices of Water Management

The stories in this month’s Aqueduct News Roundup are focused on two central themes. The first theme is the importance of data in water management: February saw the introduction of compelling new data sets, as well as water users in the private and public sectors coming to grips with the importance (and difficulty) of acquiring good water data. The second theme is cost: several stories emerged in February that demonstrated the sometimes staggering price tags associated with water for governments and companies alike.

Shale Gas: Time to Look Before We Leap Any Further

Shale gas is a game-changer for global energy supply. It is already transforming the U.S. energy outlook, and is expected to deliver over 40% of domestic gas production by 2025 (Figure 1). Other countries and regions, notably Europe and China, may soon follow suit, in a repeat of the early 20th century oil rush.

Opinion is bitterly divided, however, over the environmental risks and benefits of this abundant new source of energy – so much so, that the different sides struggle to agree even on basic facts. The debate is raging over two key issues – on-the-ground impacts to water, air, communities, land use, wildlife, and habitats; and the broader energy and global warming implications of developing shale gas.

EPA Mercury Rules: Keeping the Lights on While Removing Toxics from Our Air

Next week the U.S. Environmental Protection Agency is expected to finalize new rules to reduce mercury and other toxic air emissions that will affect dozens of antiquated power plants currently operating without pollution controls.

These rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will new EPA mercury rules influence the electricity system? This post updates earlier assessments by taking a close look at recent studies on the reliability of the electricity grid to answer that question.
